Abstract

L'invention concerne un élément ou ensemble de protection (10) utilisé dans un pulvérisateur à usage agricole pour lutter contre les pulvérisations susceptibles de se déposer sur un capteur (20) qui se trouve, de préférence, dans un boîtier (27) doté d'une lumière (19). L'élément ou l'ensemble de protection (10) résiste à l'infiltration de tout liquide ou de toutes autres particules aériennes dans une zone contenant le capteur (20) et une lumière quelconque (19). Le boîtier présente des passages ou canaux (11, 12, 13) acheminant l'air entre les obturateurs d'extrémité (21, 24) et via les passages latéraux (12, 13) vers des ouvertures (14, 15, 17) vers les zones (16, 18) où l'écoulement d'air est nécessaire pour protéger le capteur et une lumière. Un premier obturateur d'extrémité (21) présente une partie saillante (22) destinée à recevoir un tuyau d'air. Un second obturateur d'extrémité (24) délimite un trajet d'écoulement entre les passages principal (11) et latéraux (12, 13). L'élément ou l'ensemble de protection (10), le capteur (20) et les lumières (19) peuvent être montés sur une plaque (35), le capteur et une des lumières se trouvant en communication avec le sol sous la plaque grâce aux ouvertures (32, 33) pratiquées.
